AXLE-TRIMMING DEVICE.

Application filed January 10, 1913.

To all whom it may concern:

Be it known that I, WILLIAM E. WILSON, a citizen of the United States of America, residing at Detroit, in the county of Wayne andState of Michigan, have invented certain new and useful Improvements in Axle- Trimming Devices, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to axle trimming machines and consists in a construction whereby the axle may be simultaneously trimmed at a plurality of spaced points or trimmed at one of said points only; to provide such a device in which the distance between the trimmers or knives may be easily and quickly varied so as to permit the machine to be employed for axles of various sizes.

To this end the invention resides in the peculiar construction, arrangement and combination of parts as will more fully hereinafter appear and as particularly pointed out in the claims.

In the drawings,Figure 1 is a perspective view of a device embodying my invention; Fig. 2 is a central section therethrough, illustrating the machine applied to an axle; and Fig. 3 illustrates a detail of construction.

In the preferred form of my inventlon as illustrated in the drawings, A designates a frame composed of spaced side members B and O and end members D and E, and F is a sleeve for engaging the axle Gr arranged centrally of and upon which the side members are journaled. The sleeve is secured to the axle against both rotary and longitudinal movement as by means of set-screws H. Upon opposite sides of the frame are supports or carriers I I for the trlmmers J K and these supports are carried by screws L M each passing through alined apertures N O in the side members of the frame. Intermediate the sidemembers are sprockets O P having internally threaded hubs Q, en-

gaging the screws L M and provided with teeth R adapted to be engaged by lugs S T arranged upon the sleeve F at substantlally diametrically opposite points.

The knives or trimmers J K are each preferably arranged in a socket U on the inner face of the support and are longitudinally adjustable in the socket, the trimmer being secured in its adjusted position by a setscrew V. Both supports are provided with Specification of Letters Patent.

openings W in axial alinement with the sleeve F so as to permit the axle to pass therethrough, while the handle WV for rotating the frame and the trimmer supports is attached to the latter, as the member I.

Since the distinction between the points to be trimmed on the axle vary, it is desirable to have the knives relatively adjustable. This is preferably accomplished by mounting the inner support upon the screws L M so as to be adjusted longitudinally thereof. Thus, the carriage I has apertures Y Z through which the ends of the screws L M pass, and the latter have nuts A B positioned upon opposite sides of said apertured portions of the carriage I for clamping the latter in its adjusted position.

In operation assuming that the shoulders C D of the axle are to be trimmed, the trimming machine is engaged with the axle as shown in Fig. 2 and clamped in place by means of set-screws H, removable bushings E being employed for properly centering the axle in the sleeve F. The support I is then positioned so as to properly engage the trimmer J with the shoulder C and the support I longitudinally adjusted upon the screws L M through the medium of the nuts A B to engage the trimmer K with the shoulder D. The machine is then turned by the handle, revolving the knives about the axle. During the rotation of the machine the sprockets are carried about the sleeve and the sprocket teeth engage with the lugs S T, at a certain point in the travel of the sprocket. Since the lugs are arranged at substantially diametrically opposite points the teeth of each sprocket will engage once with each lug during one revolution of the frame, and as will be readily apparent, every time the sprocket teeth contact with the lug the sprocket will be slightly rotated. Also the rotation of the two sprockets 'is simultaneous. This effects a slight inward movement of the trimmer supports, thereby automatically, properly feeding the knives inward.

If one shoulder is to be trimmed less than the other, when the trimming operation thereon has been finished, the knife may be moved out of OPBIZLtlXG relation to the shoulder by releasing the set-screw V and drawing the knife outward in the socket U. Likewise when only one shoulder is to be trimmed, either knife may be rendered inoperative as before mentioned.

While I have described the preferred form of my invention, I do not desire to.

limit my protection to the exact structure illustrated herein.

WVhat I claim as my invention is 1. An axle trimming device comprising an axle engaging member, a frame rotatively mounted on said member, spaced spaced side members connected by top and bottom plates, spaced trimmer carriers arranged at the inner and outer sides of the frame and provided with apertures alining with the aperture of the axle engaging member, a pair'of feed screws connected to said carriers and adapted to simultaneously Copies of this patent may be obtained for longitudinally adjust the carriers upon an adjustment of the feed screw, complementary cog Wheels arranged within the frame upon opposite sides of the axle engaging member, said feed screws passing through said rotative frame and the hubs of said cog wheels, the hubs of the cog wheels haying a threaded engagement with the feed screws, diametrically opposed lugs mounted upon the axle engaging'member adapted to intermittently engage the cog wheels during the rotation of said frame whereby the carriers are intermittently longitudinally adjusted, trimming'members arranged upon said carriers, one of said carriers being longitudinally adjustable upon the feed screws independently of the opposite carrier, and means for securing the carrier in its adjusted position upon each of the said feed screws, comprising -nuts having threaded: engagement with the screws and arranged upon opposite sides of the-carrier.
